ECUFlash - Getting close!

photoshop and gimp both have the capability of editing photos.

but with a cloned/pirated ECUtek rom flashed on your ECU (or a fake license key), unless you've got a vendor's license and software then you're still not able to edit the map you pirated. it would be read only without those tools.

whereas when using OFT/BRZEdit/romraider/ecuflash the end user could edit their tunes at their leisure.

yep, i would guess number of folks would rather use familiar ecutech interface and features they know how to access.

yep, so does ecutech and OFT/BRZEdit/romraider/ecuflash

it's like saying that if you have a pirated photoshop license key and software installation binary or disk then once you install and register this photoshop with pirated key you will only be able to see the images but not modify or save them.
the clones would only be used for figuring out the licensing algorithm/handshake between the tune and software using authentic cable.
as for modifying cloned ecu, if you're interested, using the original cable - you should ask shiv if it's doable, i would guess yes since he was able to flash back to stock tune.

but again, these are just my speculations and you might be right

neither do I care. when I decide on what to get - I will just pay the money to support the solution I like.
imo, OFT shouldn't have tried reading and deciphering EcuTech tunes. This is IP of other people and that's how they make money. Now though it's been compromised. Now that BrzEdit allows reading and flashing free tunes from OFT it also may hurt sales of OFT. It's a war out there.

There is no "deciphering" of ecutek tunes. They use the same map addresses as the stock tune. And we read an ecutek rom using the standard read protocol used to read stock roms. We won't even bother trying to crack the ecutek security because, IMHO, it's not necessary or even worth doing given other (better) options.

In fact beacuse of the STUPID DMCA law it would even be illegal.
The DMCA makes even attempting to reverse engineer ANY encryption illegal. That is why it is even illegal to make a pdf or *.doc viewer without permission from the original vendor since the compressed nature of those files are considered "encryption".

If I made a hammer with encryption on it, it would be illegal to reverse engineer the hammer. That is how stupid the DMCA is.

oh man. shit just got real.

Here is a full ROM for ZA1JA00C to get you started. I'll be posing up a beta for and EcuFlash version that does the "OEM style" 0x8000-0x13FEFF reads and writes in the next day or so, just to get you started while I work on finishing up a kernel based reflash which will be quicker and more flexible, along with being able to read out the full ROM. Since there is no longer a kernel loader in the stock ROM, I will be adding a patch to allow for this. I'm also working on another patch to add fast and complete logging capability.

just part of the latest update on romraider...

Nice! Very excited to see where this goes.

Very cool stuff! So correct me if I'm wrong, the only expendature is a $170 tactrix cable?

assuming you know how to tune yourself, then yes.

I don't, though I'd love to learn how to. I'm assuming as Romraider/EcuFlash make their way to the BRZ/FR-S market people will adopt, tune, and maps will be available.

Tactrix cable and ideally a wideband O2 gauge (iirc innovate's can log alongside the romraider stuff).

Also a k-line obd ii cable could be used as a Tactrix cable (ver 1). Not sure if a generic k-line cable will work with the new can bus ecu we have.

Yep innovate's wideband plugs right in.

Im really interested in how the DI tables look. After seeing how much is addressable it should be interesting. Looks like you can squirt whenever and wherever you want. That's a lot to explore.

ordered one the other day in anticipation of this coming out. Granted, i likely won't be using it on my car right away unless my tuner is ok tuning in it. but i'd be more than happy to help out some locals if they want to be one of the firsts to try.

I just want to log for now.

this doesn't work on the latest ecuflash builds (anything past 1.28 i believe, as that is the newest version that i could get to recognize a standard j2534 cable). the newer versions require the tactrix branded cable, though that appears to be easily defeated with dongle cracking tricks if you were so inclined (unless you already own a bus pirate, you probably don't wanna go that route ).

best to save the trouble and buy the tactrix cable as it's cheap, has cool features (onboard logging, and the innovate plug you mentioned) and is a very good cable for the price.
